I’ll say that when I transitioned to an EV from a 20 year old SUV, the torque difference was extreme. Adjusting to that and learning 1 pedal driving at the same time… it could cause an accident, for sure.
I went from 60ps ICE to 300kW dual motor EV and the only problems I have is when overtaking on the motorway. I used to have to put the pedal to the floor to go from 60 to 70 mph. Now when I floor it in my EV at 60mph I’m at about 100 in a few seconds, it’s frightening.
EVs are definitely unnecessarily fast for retards like me
Images of the crash have circulated widely online, along with a rumor that the crash was caused by a valet—whom Tesla CEO Elon Musk publicly mocked. But now, multiple outlets report no valet was involved, just one dunce of a Tesla owner. Or should we say former Tesla owner?
Ok so the truck with a stainless steel exterior that actually rusts, that is bullet proof but only against 9mm rounds, this electrically powered thing that is gonna have you survive the apocalypse (where I’m sure the cell networks and electrical power grid will be functional)…
…this things wheel’s come off when you hit a… 10 inch high concrete slab at… 30 mph? Less?
I mean, I get thats a bit much to ask from all but a military grade MRAP or L-ATV or something… but isnt that /basically/ what Elon has marketed this thing as? An apocalypse proof vehicle?
If only the guy had crashed it into a decently deep fountain we could see how well its amphibious mode works.
Is that feature still in the ‘fever dream’ stage of development or do they actually offer it as additional feature?
It takes 3-4 days to fully charge my car 0-100% using a 120v wall plug. That’s about 1500W, which can be produced by 3-5 panels depending on their size.
That’s the slowest charging method using not a lot of panels. I would also hope you’re not planning on regularly driving 200-300 miles to need this much charging.
EV Battery Capacity is measured in Watt Hours, not Watts.
If you had 1500 Watts Hours in an EV Battery… that’d be about 1/10th a charge of the earliest EVs with roughly 10 kWh batteries and less than 1/100th of the CyberTruck’s approximately 123 kWh battery pack.
Yes, 3 to 4 smaller consumer grade solar panels … really more like 8 to 10… can have a cumulative energy production of 1500 Watt Hours…
But Watts are not Watt Hours. And 1500 Watt Hours is an extremely small amount of energy in terms of an EV.
I entirely do not mean to be a dick here, I’m genuinely curious as to what you are actually trying to describe.
Sure it would! But, you know - forage locally. Like within a few kilometers.
My ID.3 gets much better range per kWh than that brick on wheels, and I’d be able to build a solar farm for the difference in price… I doubt the brick will ever see dirt roads (they slide off easily, it seems).
Get an EV, by all means, but the CyberBlock is the dumbest vehicle around. A monument to arrogance.
How long would it take to fully charge a CyberTruck on Solar Panels?
So, as I am currently aware, the best consumer available solar panels in the US are 22.8% efficient, meaning 228W per square meter.
Assuming 12 hours of day, 12 hours of night, and Fixed Panels, you end up with roughly a 25% efficiency loss from that first efficiency figure, factoring in dust build up, inverter/battery system inefficiency, temperature dependent efficiency loss, average cloud cover and numerous other factors.
22.8 * .75 = 17.1
Sooo… to generate a full charge of CyberTruck, roughly 123 kWh…
171 watt hours * X sq m * 12 hours of daylight =
= Y watt hours generated per day.
Ok… so lets target Y as a full charge in one day.
171 watt hours * X sq m * 12 hours per day=
= 123000 watt hours per day
Solve for X.
171 x 12 = 2052
123000 / 2052 ~= 60
60 square meters of solar panels.
To be able to fully charge a Cyber Truck.
In the apocalypse.
So I hope you also have a small militia to guard your small compound of easily broken or damaged solar panels in the apocalypse.
Say youve got an array of 1x1 meter panels on the ground, spaced half a meter each with a fence around it, 6 rows of 10, then a meter to a fence.
The panels are angled at 35 degrees , so their foot print size is more like 1m x ~0.9m
So thats:
61 + (60.5) + 2 = 11m
x
100.9 + (100.9*0.5) + 2 = 15.5m
So basically, you need a plot of land roughly 170.5 sq m, or roughly 1534.5 sq ft just for solar panels.
So basically, in the apocalypse, youre gonna have something like your entire front yard as a solar panel field.
Estimated cost of setting this all up would be… what, nearly 200,000 dollars if you build the entire thing yourself, double that if you pay people to build it for you? Months of build time, half a year if you do it yourself?
Seems like a very practical way to prepare for and survive an apocalypse. Very inconspicuous.
Spend an absurd amount of money and time to be able to drive at most 175 ish miles away and then back to home base, never able to go further away in case of i dont know a mass group of starving violent people, unless you know a string of buddies every 330ish miles who /also/ have their own solar front yards they’ll just agree to let you use.
No, there are no false assumptions, the rough 25% degrade in efficiency is based on articles that cover this sort of thing for people trying to make their houses go solar that have done all the math on this.
Sure, depending on your /exact/ set up, certain parts of this will vary slightly, but you still end up in the ballpark of needing a roughly suburban front yard sized solar array and battery/inverter set up to charge a CyberTruck off of one day’s electricity.
Now, having a much smaller solar array to charge maybe an E-Bike?
Thats a faaaaar more apocalypse friendly concept.
It doesnt matter if certain other electric vehicles are slightly more efficient in terms of range per kWh: you are still gonna end up needing a fairly large solar array.
An EV for an apocalypse scenario is ludicrous.
You wont have a home charger or network of chargers if the grid goes down, and if it takes a stupendous amount of effort and time to set up a solar array giving you the ability to basically light local foraging in an EV…
A simple bicycle is faaar more practical, and an E-Bike gives you an enhanced ability to do that for faaar less investment.
Or you could have a gas powered vehicle with fuel stabilizer added to the gasoline. Thats pretty cheap and easy to stock pile, and you could put said fuel cans in your car for actual extended range.
Sorry, theres no societal collapse scenario where EVs make any sense.
They simply require /infrastructure/, and the hallmark of an apocalypse scenario is /infrastructure is broken/.
They simply require /infrastructure/, and the hallmark of an apocalypse scenario is /infrastructure is broken/.
See that’s where your argument for gas vehicles breaks down. You’re not going to be running a refinery in your back yard. Gas vehicles require a ton of infrastructure. It’s just much more widespread currently.
Lets assume you’re doing 200 miles of driving each day (you’re the one insisting on using a full EV battery daily), that’s 2 days per gas refill. Assuming you’re siphoning gas from nearby vehicles (since there is no electricity to charge EVs or run gas pumps at the local station), you’re going to run out of gasoline very quickly in your local area.
So while I can agree that day-to-day an ebike is decent transportation, assuming it’s safe to be outside in the sun for such extended periods. A gas vehicle is absolutely terrible in an apocalypse. An EV works well for decent range and will sure as heck get your further than going on foot.
For someone who likes acting clever you sure did miss a lot of very obvious things in your speech.
There are many ways of generating electricity and most are fairly easy to establish if you know how. A petrol engine requires fuel that is pretty difficult to make and denatures fairly rapidly, they can’t run on ethanol or anything easy to make so well rapidly behind useless. Diesel lasts slightly longer and biofuels will work fairly well but take a lot of effort compared to electrical generation.
There is no doubt if you had an electric car after society collapsed you’d be far better off longterm. Especially as many areas are already solar and wind powered and would still have power.
Ah so your apocalypse vehicle solution requires setting up a bunch of infrastructure (build your own wind turbine? Dam? Solar array? Molten salt nuclear reactor?) while everyone is running around killing everyone else for food and water, as opposed to having a decent sized stockpile of petrol/gasoline with fuel preservative or diesel that could be easily and inconspicuous stored in a garage or even apartment.
You are also at least /plausibly/, though not /likely/ to be able to find some gasoline or diesel somewhere in an apocalypse scenario.
You are not likely to find a working power grid in an apocalypse scenario, not until years or decades later after the survivors of the initial phase of mass panic, starvation and murder have begun to meaningfully reestablish something resembling the previous societies.
And you kind of have to survive this initial phase for the ‘long run investment’ angle to make any sense.
Please, unironically please tell me what areas in the US are 100% powered by solar or wind. I am fairly certain there are none, excepting possibly some Tribal Lands (theyre not going to let you in) or basically communes in the middle of nowhere (they are also not going to let you in).
I’m from WA originally and to the best of my ability to research, WA is one of if not the most renewably powered states in the country, getting around 2/3 of its power from dams and other renewable sources.
I genuinely have no idea what youre talking about when you say there are areas of the US that are entirely solar and wind powered. Electrical grids are part of huge interconnected networks and they do not neatly subdivide into zones that are and are not totally renewably powered.
Sure, maybe a certain neighborhood has houses covered in solar panels. Thats great! But what that realistically ends up as is a situation where that neighborhood has a good deal less draw during the day, but still relies on a dam or coal plant or wind turbines somewhere to fill up the rest of the draw, and then all of that draw at night.
None of that load balancing happens in an apocalypse scenario. The grid stops working. No more power to cover the rest of that draw. You can /maybe/ run the AC/Heat on low all day, /or/ your refrigerator in your solar house, but plug in a hair dryer or your PC or EV and drain your batteries quite rapidly, now your refrigerated/frozen food thaws and goes bad and/or you are either much more warm or cold than youre used to.
As previously established, youre gonna need several houses covered in solar panels all wired together, by you, CyberTruck owner, likely not a trained electrician capable of manipulating a portion of the neighborhood into a personal solar network battery/inverter system, while there are roving, likely armed mobs and small groups or even individuals desperate for anything they think valuable, edible or drinkable.
You say there are ways of generating electricity as if you can set up a micro electrical turbine in a stream that will charge a CyberTruck or other EV at rates higher than a solid month to get a full charge, or as if you have a somehow human safe RTG in your home, or have figured out how to harness the casimir effect to generate free energy… maybe you have a personal geothermal power generator?
I don’t know if you’re being purposely weird about this but whatever, I’ve watched hundreds of hours of YouTube with people doing all the things you seem to think are impossible.
Honestly I’m fine with you having the worst possible vehicle so I’m not really going to try and convince you further.
The dumbest thing you said is load balancing, like it matters if you can change your vehicle in ai night. Like going by your ideas you seem to think you think you’re going to be commuting or something.
If you are going to tell me that an MRAP or L-ATV is not built to much, much higher durability, survivability and capability standards than a consumer grade vehicle, you’re off your rocker.
Yes. Military Grade ‘stuff’ is often done by lowest bidders. Whoah, so are nearly all consumer products!
The difference in this case is fundamentally different approaches to design. Hugely different kinds of suspension systems and body design, etc.
No, its obviously not a literal indestructibility modifier.
But it sure goes a long way further toward it in many cases.
Ya,know. You have done the “unthinkable” and actually changed my mind about military grade stuff when you put it that way! This is not sarcasm, I’m for real
Hooray! I’m glad to have done the unthinkable then, aha.
Yeah, as much as there often is merit to criticizing aspects of many elements of military gear… a lot of those criticisms get overblown and recontextualized to seemingly comparable other kinds of goods or equipment in a way that kind of misses certain crucial aspects.
Maybe an actual good example of ‘Military Grade’ actually meaning ‘crap’ would be the kind of gunpowder used in the earlier production of 5.56 rounds for the first generation of M16s in Vietnam.
That is an actual case where going to the lowest bidder for what turned out to be gunpowder that burned too dirty for early M16s, combined with a lot of hype around the M16 being ‘self-cleaning’ leading to initially no or very few cleaning kits being issued… yeah that led to a whole lot of the guns jamming up.
But this doesnt mean you can just blanket point to all military grade stuff and say its garbage.
There are legitimate military-grade designations. Military-grade encryption is one. It entails a mandatory physical component. Quite expensive without even considering the logistics behind securing such a device. Not cheap by any means, and yet it really bothers me that you can buy “military-grade” encryption without the hardware for consumer products. That’s…just regular encryption guys…
For stuff that legitimately has such designations on the consumer side, it’s not just cheap - it’s incorrect, incompatible, or illegal.
What specifically gives the physical component better encryption than a pure software solution? It’s just a stream of data, anything hardware can do to it can also be done by software. Purpose-built hardware is generally faster than general-purpose hardware, but if you don’t mind the speed difference, the encrypted data should be just as secure whether a physical component was involved or its role was played by software.
I believe they are talking about systems that require the input of a … haha ‘closed source’ (meaning classified) physical hardware/software system that is completely non networked that requires a human being to be physically using /at least/ one entirely, totally sandboxxed device to complete the authentication process of accessing information on a networked device.
Kind of like an extremely more advanced version of the enigma machine + codebook system.
I may be wrong here though about specifically what they are referring to, I don’t actually have any actual experience with real milgrade cybersecurity stuff.
The sort of cheapo way to do something like this is something I’ve seen at various points in my tech industry career, basically a yubikey or similar devices.
From a birdeye view, nothing. And that’s not what the designation attempts to address. It’s not even about how fast the hardware is, as encryption doesn’t require lots of processing power and key delivery systems are relatively simple devices.
It’s about control. Encryption in general is robust and nobody directly tries to break the algorithm. Most breaches are done by bypassing the encryption entirely. By adding a hardware component, it makes it very difficult to do so. It also creates a one-way bridge for key delivery - once you put keys into the device you cannot remove it. The only option is to delete it. Most of the devices are also hardened - they emit no signals, resist interference, and have various preventions that will dump keys and software in the event the device is tampered with. Add to the fact that because it’s physical in nature and not some boogeyman subsystem buried deep in a server, you can point to it, tell someone to guard it, and put it in a vault. Most also have an accessible wipe button, which makes it easy to prioritize what gets destroyed if the need calls for it. There are many more things, but I think I made my point.
It’s still hard for the consumer market to have a physical component for encryption. Even for those that do, it’s still not robust enough. You can get legitimate military-grade encryption, with all its bells and whistles, but it’s incredibly expensive and requires specific requirements by the NSA. But afaik, there is no cheap alternative, and most of what you see being advertised is just marketing gibberish.
Perhaps another example somewhat along these lines would be ‘military grade’ laptops.
No, not (usually) the stuff marketed as milgrade, actual military grade laptops that are nearly bullet proof suitcases that can survive a bomb going off near them or being dropped out of a moving vehicle.
They also have other comms capabilities and such, but I think the main point here is … heres a thing thats /actually/ physically durable and tough, faaaar more so than basically any consumer grade laptop.
Is this a practical level of protection needed by most consumers? Probably not. But, it might be handy in an apocalypse scenario.
Maybe he had a very fast, very intense buyers remorse experience and decided the only dignified way out is to absolutely wreck the terrible investment out of spite.
As much as I hate Elon Musk, I prefer for my own sanity to believe that it wasn’t designed to kill pedestrians, it’s just that Elon is such an idiot that his version of The Homer was built without even considering them because that front just looked cool to Elon and he said they had to make it that way.
